# Frontend and API Testing Using Cypress and Postman

During a recent [Postman livestream](https://www.youtube.com/watch?v=mPZJdAH1alc) with the senior director of engineering at Mercari, Dr. Gleb Bahmutov, PhD, we wrote frontend and [API tests](https://www.postman.com/api-platform/api-testing/) using [Cypress](https://www.cypress.io/) and Postman, and then we ran them as part of a continuous integration pipeline in CircleCI. Previously the VP of engineering at Cypress, [Gleb](https://twitter.com/bahmutov) is now one of the foremost instructors on Cypress technology and has strong opinions about the importance of testing in a modern software development team.

*“If you’re a developer, and you don’t identify as a tester as well, you’re not a real developer.”* — Dr. Gleb Bahmutov, PhD, senior director of engineering at Mercari
